KU the pedants
I'm not sure the transmissions from satellites can really be compared to local RF sources, inverse square law and all that.
We must at some level be affected by electrical impulses or we'd be dead. RF itself is not necessarily bad as many ancient radio ham can attest but the pulsed combinations and RF bath we live in just might.
The human body can be quite a good antenna at some frequencies, who is to know what affect the combined RF soup and local topology has on any particular spot and over a long time?
(Note. Some strange affects can be had mixing superhigh frequencies - see "john hutchison".)
